Honeywell RedLink thermostats have different Deadbands. Why?
Why do the two Honeywell RedLink thermostats have different Auto Changeover Deadband factory settings? The THX9421R5021WW comes preset to 5°F and the TH821R1001 comes preset to 9°F. I am installing both on two air-to air heat pumps in south Florida. Heat pumps are Trane single stage heat with electric backup and single stage cool. Should I leave the Auto Changeover Deadbands at factory settings or make both the same?
